What is DSIP?
DSIP is delta sleep-inducing peptide, a naturally occurring nonapeptide with the amino acid sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu. It carries the molecular formula C35H48N10O15, a molecular weight of 848.8 g/mol and CAS number 62568-57-4 (PubChem CID 68816). Kovalabs supplies it as a lyophilised powder for laboratory research use only.
The name "delta sleep-inducing peptide" is the historical label given to the molecule when it was first isolated from cerebral venous blood; it describes the original isolation context, not a confirmed effect. It is a research peptide sold for in-vitro and non-clinical model work. It is not a sleep aid, a medicine or a product for human consumption.
Is DSIP legal in the UK?
DSIP is not a controlled drug under the Misuse of Drugs Act 1971 and is not a UK-licensed medicine. Kovalabs supplies it strictly as a research chemical for laboratory use, not for human or veterinary use and not for consumption. It must not be administered to people or animals. The buyer is responsible for handling, storage and compliance with applicable local rules. See our research disclaimer for the full terms.
How is identity and quality assured?
Every batch is released only after independent identity and purity testing. Purity is assessed by HPLC at >=99% and identity is confirmed against the expected mass for C35H48N10O15. The verified identifiers (CAS 62568-57-4, PubChem CID 68816, sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) let researchers cross-check the material against public chemical databases. Certificates of analysis are available at our CoA library.
What does the research on DSIP investigate?
The published literature examines DSIP in the context of neuroendocrine signalling and sleep-related neurophysiology in laboratory and animal model systems. None of this establishes a benefit, effect or outcome in humans, and DSIP is not a licensed medicine. For the mechanistic detail, isolation history and a referenced summary of the model-system literature, see the DSIP research monograph.
Synthesis and supply
DSIP is supplied as a lyophilised (freeze-dried) white to off-white solid. For bench work it is reconstituted with a suitable solvent such as bacteriostatic water, which Kovalabs stocks alongside the peptide catalogue. Store the lyophilised powder at -20C, dry and protected from light; hold reconstituted material at 2-8C. Browse related research materials in our neuropeptides category, including Selank and Semax.

- What is DSIP?
- DSIP is delta sleep-inducing peptide, a naturally occurring nonapeptide first isolated from cerebral venous blood. Its sequence is Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, with molecular formula C35H48N10O15 and molecular weight 848.8 g/mol. Kovalabs supplies it as a lyophilised research peptide for laboratory use only, not for human or veterinary use.
- What does the DSIP name mean?
- The name delta sleep-inducing peptide describes how the molecule was first characterised when isolated decades ago, not a verified function. It is the established chemical name and abbreviation expansion only. DSIP is a research chemical, not a sleep aid or a medicine, and is supplied strictly for laboratory research use.
- Is DSIP legal in the UK?
- DSIP is not a controlled drug under the Misuse of Drugs Act 1971 and is not a UK-licensed medicine. Kovalabs supplies it as a research chemical for laboratory use only. It cannot be sold for human consumption and must not be administered to people or animals. The buyer is responsible for lawful handling, storage and use.
- Is DSIP intended for human use?
- No. DSIP is sold exclusively as a research chemical for in-vitro and non-clinical laboratory work. It is not for human or veterinary use, not for consumption, and not a dietary or therapeutic product. It must not be administered to people or animals under any circumstances.
- Has DSIP been shown to be safe or effective in humans?
- No. The published literature on DSIP concerns laboratory, in-vitro and animal model systems. None of it establishes a benefit, effect, safety profile or outcome in humans, and DSIP is not a licensed medicine. It is supplied solely as a reference compound for non-clinical research.
- Is all DSIP the same?
- No. Purity and identity vary by supplier and batch. Kovalabs releases each batch only after independent testing: purity assessed by HPLC at >=99% and identity confirmed against the expected mass. A certificate of analysis is available so researchers can verify exactly what they receive.
- What are the molecular identifiers for DSIP?
- DSIP has CAS number 62568-57-4 and PubChem CID 68816. Its molecular formula is C35H48N10O15, with a molecular weight of 848.8 g/mol and the amino acid sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu. These identifiers let researchers cross-check the material against public chemical databases.
- How is DSIP supplied and reconstituted?
- DSIP is supplied as a lyophilised (freeze-dried) white to off-white powder. For bench work it is reconstituted with a suitable solvent such as bacteriostatic water, which Kovalabs stocks alongside its peptide range. Reconstitution is a laboratory preparation step only; the material is not for administration.
- How should DSIP be stored?
- Store the lyophilised powder at -20C, kept dry and protected from light. Once reconstituted, hold the solution at 2-8C. Proper storage preserves peptide integrity for laboratory research. DSIP is supplied for research use only and is not for human or veterinary use.
- Where can I buy DSIP in the UK?
- Kovalabs supplies DSIP to UK researchers with batch certificates of analysis and UK despatch. The peptide is provided as a lyophilised solid, >=99% HPLC, for laboratory research use only. See the certificate of analysis at our CoA library before ordering.
- Does DSIP come with a certificate of analysis?
- Yes. Every batch is released after independent identity and purity testing, and a certificate of analysis documenting HPLC purity and identity is available. You can view CoAs at our CoA library to confirm the batch specification before purchase.
- How does DSIP compare with Selank or Semax?
- DSIP, Selank and Semax are distinct research peptides with different sequences and molecular identities; they are not interchangeable. DSIP is the nonapeptide Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu. All three are supplied by Kovalabs as lyophilised research chemicals for laboratory use only, not for human or veterinary use.
- Is DSIP a peptide?
- Yes. DSIP is a peptide, specifically a nonapeptide of nine amino acids with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu. It is not a steroid or a small-molecule drug. Kovalabs supplies it as a research peptide for laboratory use only.
- Where can I read more about DSIP research?
- For the isolation history, mechanistic context and a referenced summary of the model-system literature, see the DSIP research monograph on the Kovalabs blog. The monograph frames all findings as non-clinical research and makes no human benefit or outcome claims.
